SPRING-BED.

SPECIFICATION formingpart of Letters Fatent No. 502,118, dated July 25,1893.

Application filed March 7, 1893- To all whom it mag concern:

Be it known that I, OLIN R. GOULD, of Dayton, in the county of Websterand State of Iowa, have invented a new and Improved Spring-Bed, of whichthe following is a full, clear, and exact description.

My invention relates to improvements in sprlng beds, and the object ofmy invention is to produce a cheap and simple spring bed which is strongand durable, which has 'an even and flat top surface, and which is adapted to offer a level and extremely easy surface upon which one may lie.

To this end my invention consists in certain features of constructionand combinations of parts, as will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts'in both the views.

Figure 1 is a broken plan view of thebed embodying my invention; andFig. 2 is a broken side elevation of the same.

The bed is provided with a suitable frame composed of longitudinalparallel slats 10 and cross pieces 11 which are secured to the slats,butthe frame may be made in any convenient manner. Upon the slats atnecessary intervals are spiral springs 12 which are like the ordinarybed springs being largest at the top so that they may close down into asubstantially flat position under heavy pressure, and these springs aresuspended in an upright position by the set springs 13, which are smallspiral springs having their upper ends attached to the main spirals l2and their lower ends secured to the slats of the bed frame.

The bearing or lying surface of the bed is composed of concentric spiralsprings 14 and 15 and their strengthening cross springs 16. The springs14 and 15 are each formed of relatively small wire twisted into aspiral, and the springs, as above remarked, are placed concentrically, apair of springs 14 and 15 being placed centrally between every four ofthe main spiral springs 12, as clearly shown in Fig. 1.

The springs 16 cross each other at right Serial No. 464.931. on model.)

angles and extend diametrically across the concentric springs 14 and 15,the ends of the springs 16, which I will term guy springs, being securedto the tops of the adjacent spiral springs 12.

The'springs 16 are secured to the springs 14 and 15 by simply twistingthe wires of the springs together so that they will interlock,

or they may be fastened together in any convenient manner.

It will be noticed that none of the guy springs 16 run parallel with theslats 10, so that there is no great strain upon any particular springwhen a person sits on the edge of the bed, and the arrangement of thesprings is such that the bed is provided with a perfectly level top andthe strain caused by a weight on the bed is sufficiently distributedover the several springs so that the bed lies easily and no springs areunduly strained.

It will be observed that all the springs are spiral springs, and it iswell known that these form the most yielding support so that the bed isextremely easy to lie upon. The spiral coils forming the springs 14, 15,16, are of small wire which is desirable, and the special arrangement ofsuch springs enables them to mutually support and brace each other.

Having thus described my invention, I claim as new and desire to secureby Letters Patent A bed spring comprising a frame, a series ofvertically extending spiral springs thereon, concentric horizontalcircular spiral springs in the space between each four vertical springsand of lighter material than the latter, and a pair of straighthorizontal spiral springs interlocked at their middle with each other atthe center of the innermost circular spring, interlocked beyond theirpoint of intersection with both of said circular spiral springs at theseveral points of intersection and connected at their ends with theupper coils of the vertical spiral springs, substantially as set forth.
